| 摘 要： | 影像的几何质量影响着影像的定位精度。以光束法为平差模型,对高几何质量影像与高分辨率低几何质量影像的联合平差定位精度进行了实验与分析。研究结果表明:在高分辨率低几何质量的条带覆盖影像中加入单张高几何质量的影像进行联合平差,即可提高影像的定位精度;条带内影像的重叠度愈低,联合平差对影像定位精度的提高愈为明显。

| Abstract: | The geometric quality affects the positioning accuracy of the image.This paper experimented and analyzed the positioning accuracy of combined adjustment of high geometric quality image and high resolution and low geometric quality image based on bundle adjustment.The results showed that the combined adjustment of a single high geometric quality image and high resolution and low geometric quality strip iamge can improve the image positiong accuracy.The lower the image overlap in the strip,the more obvious improvement of the image positioning accuracy by the combined adjustment. |

| Keywords: | geometric quality of image multi-sourceimage multiresolution bundle adjustment positioning accuracy |
